I have an efm boiler w/2 heat zones. When the second heat zone turns on only the pump runs till the boiler temp goes down and then the boiler kicks on. When the first heat zone turns on the boiler and the pump turns on at the same time. My question is can I wire and how do I wire only the pump to turn on when the first heat zone turns on? The boiler turn on and off by it self to keep temp in it,so I think I can do this but I'm not sure how.
Now the reason I want to do this. The wife likes to play with the thermostat, Last year I set it at 68 get the fire set and then come home from work some days and it's turned up to 72-74 and there a lot of unburnt coal from the boiler running till the house comes up to temp even though the boiler is up to temp it just keeps running till the thermostat shuts it off.
Any help would be great so I don't have to duck tape her to the chair before I leave for work.
Only kidding about the duck tape but I have thought about it.
